This review discusses the roles of androgens and androgen receptors in skin-related disorders and suggests that targeting androgen receptors may be a more effective treatment strategy.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

This review discusses the potential autoimmune pathogenesis and various contributing factors of alopecia areata, noting that current treatments remain palliative while emerging therapies offer new hope for extensive cases.

This review discusses the advancements in understanding and treating androgenetic alopecia and alopecia areata but reports no clinical findings; the authors emphasize the need for further research on molecular control mechanisms.

This review discusses medical and surgical therapies for alopecias in Black women, focusing on the impact of hair-care practices and the importance of patient education, but reports no new clinical results.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

This study highlights that prolonged voriconazole use is linked to an increased risk of aggressive cutaneous malignancies like squamous cell carcinoma, necessitating careful monitoring of drug levels to manage adverse effects.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

This study found that the EDAR 1540T/C genetic variant is significantly associated with hair thickness variation in Japanese populations, enhancing previously observed associations in Southeast Asian groups.

This review discusses androgenetic alopecia and alopecia areata through a systems biology lens, emphasizing the role of multi-omics data integration to explore molecular mechanisms and potential therapeutic strategies, but offers no new clinical results.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This review updates on the understanding and management of eating disorders, noting substantial progress over 30 years but highlighting the need for revised classification, clarified pathogenesis, and improved treatments.

This review discusses the safety of testosterone therapy for postmenopausal women and concludes that, aside from hirsutism and acne, it appears safe at physiological doses for several years, though more long-term studies are needed.

This study found that three genetic loci, including the newly identified JMJD1C, are associated with circulating testosterone and dihydrotestosterone levels, explaining a small portion of their variance in European men.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This study found that topically applied minoxidil was more effective than nitroglycerin and placebo in enhancing penile diameter, rigidity, and arterial flow, with the most pronounced effects in patients with neurogenic impotence.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

This review analyzed randomized controlled trials on alopecia areata treatment and found that while several treatments showed effectiveness, most studies had limitations affecting their interpretability.

This review examines factors influencing dermatophyte infection in companion animals, focusing on prevalence, clinical signs, pathogenesis, immune response, and the impact of cortisol and cytokines, but reports no new clinical results.

This review discusses the emerging "endocrine phenotype" of COVID-19, highlighting the implications for managing diabetes, obesity, vitamin D deficiency, and other endocrine conditions in affected patients.

This review discusses the role of the hedgehog signaling pathway in hematological cancers and its potential as a therapeutic target; it reports no new clinical findings.

This study found that although diabetic patients undergoing a very low calorie diet experienced faster weight loss initially, those on a conventional diet and exercise plan maintained weight loss more effectively over five years.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study found that eosinophils are a useful diagnostic feature for alopecia areata, especially when the typical "swarm of bees" lymphoid infiltrate is absent, helping differentiate it from trichotillomania.

This review discusses the basic biology of apoptosis and its relevance to skin diseases, without presenting new research findings.

This study found that sex steroid hormone receptors are largely maintained during the transformation of skin appendages to neoplasms, except for androgen and estrogen receptors in sweat and sebaceous gland tumors.

This study found that finasteride treatment improved cardiac function and reduced heart failure progression in mice, suggesting it could be a potential therapy for pathological cardiac hypertrophy and dysfunction.
